Yianerm Outdoor Sports Men’s Quick Dry Sleeveless Cycling Base Layer Tank Top Vest

XXXL size was something like XSMALL also, the re is not tag listion what material was this garment made of. This should be an unacceptable safety problem! Do not buy from this source!

Was extra small

Update! After 7 months of riding (rotating 4 pair) and over 2,000 miles, all of them are still going strong. Normal wash cycle and hang dry after each ride has not been an issue for these base layers. It was also a good test to see how well they do in hot weather and ive been very pleased. Good stuff! (Original review from Dec. 2018: So, I'm not a fan of usurping other's reviews, but in this case....a couple of things: One review refers to not knowing what the material is, however if you read the product description, it reads "98% polyester". Granted, I'm guessing the other 2% is going to be something like Lycra for the stretch. As far as sizing goes, base layers as SUPPOSED to be skin tight. They're technically designed to be worn under a jersey and pull moisture off the skin for rapid evaporation. These are not t-shirts. I'm 69" (175cm) tall and went with large...perfect length and shoulder width. I just got a couple of them, so 4 stars due only for the fact I have no reference to longevity at this point.)
